Dimension Scores
Achieves Cybenetics Platinum and 80 Plus Gold certifications, delivering 1600W with tight voltage regulation (0.5% on 12V rail).
Features a 135mm FDB fan with iCool intelligent control, often remaining off under significant loads, and holds a Cybenetics LAMBDA A acoustic certification.
Utilizes 100% Japanese capacitors and robust construction, with integrated TempGuard sensors in the 12V-2x6 cables.
Fully modular design allows for custom cable routing, and includes two native 12V-2x6 cables, though some users find the sheer number of cables can be messy.
Best For
- High-end gaming PCs with multiple power-hungry GPUs (e.g., RTX 5090).
- Workstations running intensive rendering or simulation tasks.
- Future-proofing a build for upcoming ATX 3.1 and PCIe 5.1 hardware.
- Users prioritizing minimal coil whine in their system.
Not Recommended For
- Budget PC builds where 1600W is excessive and cost-prohibitive.
- Compact ITX or SFF cases due to its standard ATX form factor and potential weight.
- Users who prefer pre-sleeved or custom-colored cables out of the box.
Watch Out For
- The 7.09 in length might be a tight squeeze in smaller ATX cases, so measure your case before buying.
- Despite the 220% power excursion support, you won't benefit unless your components actually demand those spikes.
- The 12V-2x6 cable's green plug needs to be fully seated to disappear, which can be missed if you're not paying attention.
- While it has a 10-year warranty, needing to use it means your system is down for repairs.

What Buyers Say
This ASRock 1600G PSU is surprisingly quiet for its wattage, with one user noting the fan didn't even spin up during simultaneous Cinebench and Furmark runs on a 7950x + 5090 system. The dual 12V-2x6 cables with their green plugs and TempGuard are a specific highlight, making proper seating obvious and adding a layer of safety. While it's praised for its high power capacity and robust build, some users have pointed out its considerable weight and the potential for cable clutter due to its fully modular nature.
“Dude, I got this for my 5090 and it's quiet as heck, no coil whine like my old one, and those 12V-2x6 cables actually have a temp sensor, which is kinda wild. Worth it if you're going all out.”
Common Praise
- Fan stays off during heavy gaming, contributing to a quiet system.
- Dual 12V-2x6 cables with bright green plugs make correct seating easy to verify.
- Minimal coil whine, even when uncapping framerates in demanding games.
- Cables are high quality and flexible, aiding in routing.
- Exceptional electrical performance with tight voltage regulation.
Common Complaints
- Can be noisy under extreme, sustained loads.
- The 7.09 inch length and nearly 10 lb weight can be challenging for some case installations.
- Fully modular design, while flexible, can lead to a 'spaghetti' of cables if not organized.
- Not universally compatible with all pre-built systems.
Ownership Tips
- The green color on the 12V-2x6 connector is a visual cue for proper seating; if you still see green, it's not fully in.
- Comes with two 12V-2x6 cables, which is clutch for dual high-end GPU setups or future-proofing.
- The PSU's fan often doesn't spin up unless you're really pushing the system, like running benchmarks simultaneously.
- The weight is noticeable; plan your case installation carefully, especially if mounting in a less accessible spot.
Frequently Asked Questions
Does this PSU come with the new 12V-2x6 cables?
Yes, it includes two native 12V-2x6 cables, designed for modern high-power graphics cards. These cables feature a dual-color design and TempGuard for safety.
Is this power supply quiet under load?
Under typical gaming loads with a high-end system (like a 7950x + 5090), the fan often remains off. Some users have reported it can get noisy under extremely heavy loads.
What does 'Cybenetics Platinum and LAMBDA A Certified' mean?
Cybenetics Platinum indicates very high power efficiency, similar to 80 Plus Platinum. LAMBDA A certification signifies a low noise output level, making it one of the quieter PSUs available.
Can I use this PSU with older components?
Yes, it's backward compatible with older components, but its ATX 3.1 and PCIe 5.1 readiness means it's optimized for current and future hardware. It might not be compatible with all pre-built systems.
What is the warranty period for this power supply?

Buying Guide
When you're looking at a power supply like this, you're basically buying the engine for your PC. The wattage (1600W here) tells you how much power it can deliver, which is crucial for high-end graphics cards and CPUs. 'Fully modular' means you only plug in the cables you need, which helps keep your case tidy and improves airflow. Efficiency ratings like '80 Plus Gold' and 'Cybenetics Platinum' tell you how much power is actually used by your components versus how much is wasted as heat; higher efficiency means less wasted energy and less heat inside your case.
1600W Wattage
Think of this as the horsepower of your car. 1600W is a lot, meaning this PSU can handle multiple top-tier graphics cards or a single, extremely power-hungry GPU without breaking a sweat, ensuring stable power delivery even during peak demands.
ATX 3.1 & PCIe 5.1 Ready
This is like having the latest fuel injection system for your engine. It means the PSU is designed for the newest generation of PC components, especially graphics cards, which can have sudden, massive power spikes. It ensures compatibility and stability for your cutting-edge hardware.
Native 12V-2x6 Connector with TempGuard
This is a direct, dedicated power line for the newest, most power-hungry GPUs, like a supercharger for your graphics card. The 'TempGuard' is like a built-in thermometer that shuts things down if the connector gets too hot, preventing damage to your expensive GPU.
Alternatives
If 1600W is overkill, search for ATX 3.1, PCIe 5.1 power supplies with 1000W-1200W output, Cybenetics Platinum or Gold efficiency, and at least one native 12V-2x6 connector.
